What’s New in GetFEM 1.6

Released, 2004/01/23:

  • GetFEM 1.6 is mostly a bugfix and performance improvements release:

    • Some new integration methods were added (high order methods for triangles such as IM_TRIANGLE(19) from P. Solin, K. Segeth and I. Dolezel: Higher-Order & Finite Element Methods, Chapman & Hall/CRC Press, 2003).

    • Performance of interpolation and geometric transformation inversion was much improved.

    • Support for emc2 meshes.

  • The Gmm++ library has been much improved version 1.6 and version 1.5. We have especially focused on its robustness:

    • Many bugs were fixed, especially for complex matrices.

    • QR algorithms were introduced for dense matrices.

    • A LAPACK/ATLAS interface is available.

    • SuperLU 2.0 interface.

    • Small simplification in linalg_traits structure.

    • Generic resize procedures for vector and matrices were introduced.

    • It is possible to use a column or row matrix view of a vector with gmm::row_vector and gmm::col_vector.

    • Generic gmm::reshape and gmm::conjugated functions.

    • Intensive tests with random type of matrices and vectors.
